SWITCH AND FUSE-PLUG socxn'r.

Application led January 7, 1927. Serial No. 159,645.

My invention relates particularly to switch structures and fuse-plugsockets for electric ranges, but it will be understood that thecombination and arrangement of' parts may be used in any place where afuse-plug socket is connected to a switch structure. One'object of theinvention is to independently conneet the switch structure and thefuse-plug socket to their respective bus-bars.

A further object of my invention is to so construct the connectionbetween a fuse-plug socket and a switch structure that the fuseplugsocket may be adjustedto any angle 1n' respect to the socket.

In the accompanying drawing:

Fig. 1 is a side view of a switch structure and a fuse-plug socketconnected in accordance with my invention;

Fig. 2 is a rear view; v

Fig. 3 is a view similar to Fig. 1, but. showing the socket at an anglein respect to the switch structure;

Fig. 4 is a detached face view of the fuseplug socket ;I and Fig. 54 isa detached perspective view of the fuse-plug socket.

'Ihe switch structure 1 is of any suitable type, having a body portion 2of porcelain,

' or other non-conducting material, recessed at the back for theconnections 3 and 4. The connection 3 is electrically attached to abusbar 5 by means. of a screw 17, and the body portion is held rigidlyto the bar by a screw 18 which in thel present instance 1s not anelectrical connection.,

The connection 4, in the present instance is of flat metal, shaped asshown in Fig. 4.

The connection 4 is forked, as at 10, to fit around a projection 11 ofthe fuse-plug socket 6, and 1s held in contact with the base of thethreaded shell 12 by screws 13, and extends through a slot v14 1n thesocket and shell as shown in Fig. 5. l

This connection 4 is preferably curved and bentas at 7 to lit the recess8 in the back of the body portion 2 and is electrically connected to oneterminal of the switch structure by a screw 9.

In Fig. 3 the bus-bar 15 is angularly disposed with-respect to the bar 5and the front of a range, and the connection 4 is bent so that thesocket will tit against the surface of the bar.

By making the connection inthe form substantially asshown, it can bebent to anyangle desiredto adjust the fuse plug socket in respect to thefront of an electric range. The switch structure can be attached to asin le bus-bar and the fuse-plug socket can be rmly secured to theswitch structure and to another 'bus-bar or other conductor.

1. The combination of a switch structure having a body portion recessedat the back; a bus-bar to which said structure is secured; a fuse-plugsocket having a threaded shell; a second bus-bar; a terminal screwconnecting the socket to the bus-bar; aflat metallicl connection forkedat its inner end and extending through an opening in the socket; .andscrews securing the connection to the shell and socket, lthe outer endof the connection being curved and bent to fit a recess in the body ofthe switch structure.

2. The combination of aswitch structure having a body portion; a bus-barto'which said structure is secured; a fuse plug socket having a threadedshell and slotted; a terminal screw connecting the socket with aterminal; a flat metallic connection extending'through the slot in thesocket; and means for securing the connection to the shell and socket,the outer end of the connection being attached to the switch structure.
